Under federal law, credit card issuers cannot charge over-limit fees on credit cards unless you specifically opted in to allow transactions that exceed your credit limit. If you never gave that consent, no fee is allowed, even if the issuer approves the over-limit purchase. If you did opt in, the fee is capped at $32 the first time and $43 for a repeat within six billing cycles, and it can never exceed the dollar amount you actually went over.
You Have to Opt In Before Any Fee Is Allowed
The opt-in requirement comes from the Credit CARD Act of 2009. Your issuer has to ask whether you want to allow over-limit transactions, and you have to affirmatively agree before it can assess a fee. A pre-checked box or a clause tucked into the card agreement doesn’t count. The choice has to be clear and voluntary.1eCFR. 12 CFR 1026.56 – Requirements for Over-the-Limit Transactions
A common misconception: declining to opt in does not automatically mean every over-limit purchase gets rejected at the register. The issuer can still choose to approve the transaction. It just can’t charge you a fee for doing so.2Office of the Law Revision Counsel. 15 USC 1637 – Open End Consumer Credit Plans Whether the charge goes through is up to the issuer. Whether you pay for it isn’t.
Before asking for your consent, the issuer must send a standalone notice separate from other disclosures. That notice has to state the fee amount, whether opting in could raise your APR, and that consent is voluntary. Once you say yes, the issuer confirms it in writing, and every statement that carries an over-limit fee has to remind you on its front page that you can revoke consent at any time.2Office of the Law Revision Counsel. 15 USC 1637 – Open End Consumer Credit Plans
How Much the Fee Can Be
Even after you opt in, the issuer can’t set the fee at any amount it likes. Federal rules establish safe harbor limits on penalty fees:
- Up to $32 for a first violation.
- Up to $43 for a subsequent violation of the same type within six billing cycles.
These amounts are adjusted annually based on the Consumer Price Index, so they may tick up slightly year to year.3eCFR. 12 CFR 1026.52 – Limitations on Fees The CFPB’s 2024 rule that capped late fees at $8 for large issuers does not apply here; over-limit fees stay at the $32 and $43 thresholds.
A separate proportionality rule matters more for small overages. The fee can never exceed the dollar amount by which you went over. If a purchase pushes your balance $15 past the limit, the maximum fee is $15, not $32.3eCFR. 12 CFR 1026.52 – Limitations on Fees
How Often You Can Be Charged
Two frequency limits work together. Only one over-limit fee is allowed per billing cycle, regardless of how many separate purchases pushed you further over during that period.4Consumer Financial Protection Bureau. 12 CFR 1026.56 – Requirements for Over-the-Limit Transactions
And for a single over-limit event, the issuer can charge a fee in the cycle when you first exceed the limit and then once in each of the next two billing cycles. That’s three cycles, maximum. After that, if you haven’t made any new purchases pushing the balance further over, no additional over-limit fee is allowed even if the balance is still above the limit.2Office of the Law Revision Counsel. 15 USC 1637 – Open End Consumer Credit Plans The clock only resets if a new transaction increases the over-limit amount during one of those later cycles.1eCFR. 12 CFR 1026.56 – Requirements for Over-the-Limit Transactions
The Fee Isn’t Usually the Biggest Cost
Two other consequences of going over your limit typically hurt more than the fee itself.
The first is credit utilization. Credit scoring models weigh how much of your available credit you’re using, and that factor accounts for roughly 30% of a typical FICO score. When your balance exceeds your limit, utilization on that card goes above 100%, which can pull your score down sharply, especially if you don’t have other cards with low balances to offset it. Paying the balance below the limit before your statement closing date is the fastest way to limit the damage, since most issuers report balances to the credit bureaus at statement close.
The second is a penalty APR. If you opted in, the issuer may have disclosed that going over your limit could trigger a higher annual percentage rate on your account. Some issuers treat an over-limit event the same way they treat a late payment. The opt-in notice is required to spell out whether this happens and what the higher rate would be, so check that notice or your card agreement to know whether your issuer takes this approach.1eCFR. 12 CFR 1026.56 – Requirements for Over-the-Limit Transactions
Disputing a Fee You Didn’t Authorize
If an over-limit fee shows up on your statement and you never opted in, you have strong grounds to challenge it. Call the issuer or send a secure message through your online account, reference your opt-in status, and ask for the reversal.
If that doesn’t work, you have two formal routes. Under the Fair Credit Billing Act, you have 60 days from the date the statement containing the error was sent to dispute the charge in writing. Send the letter to the issuer’s billing inquiry address, not the payment address, and include your name, account number, the amount in question, and why you believe the fee is wrong. The issuer must acknowledge your dispute within 30 days and resolve it within two full billing cycles, and no more than 90 days.5Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
You can also file a complaint with the Consumer Financial Protection Bureau, which oversees issuer compliance with the opt-in rules. Filing a complaint doesn’t guarantee a refund, but it creates a regulatory record and often prompts a faster response.6Consumer Financial Protection Bureau.

Turning Opt-In Off
You can opt in or opt out at any time for the life of the account. The law requires that the same methods available for opting in also be available for revoking consent. If you opted in by phone, you can opt out by phone.2Office of the Law Revision Counsel. 15 USC 1637 – Open End Consumer Credit Plans Most issuers also let you change this preference through their website, mobile app, or a written notice.
Once you revoke, the issuer has to stop charging over-limit fees on future transactions. Keep the written confirmation. If a fee shows up on a later statement anyway, that confirmation is your evidence for a dispute. As a practical matter, most cardholders are better off leaving over-limit coverage turned off. Without it, transactions that would exceed your limit are more likely to be declined at the point of sale, which is a brief inconvenience that heads off the fee, the score damage, and any penalty APR that might follow.
